Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of Taiwan application serial no. 112116867, filed on May 5, 2023. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The disclosure is related to a camera module and an assembly method thereof. Description of Related Art With the development of multimedia technology, digital cameras and video cameras are becoming more and more popular among consumers. People are increasingly pursuing the miniaturization of digital cameras and video cameras. At the same time, since portable electronic devices such as smart phones are thin, light, small, and easy to carry, people hope to have a camera module installed on their smartphones to enable the function of capturing object images and obtain clear pictures. However, the heat generated during the operation of the camera module causes a temperature difference with the environment. In addition, the presence of moisture in the air can cause water droplets to condense and adhere to the lens inside the camera module. In addition, even if the water droplets evaporate after condensation, they can leave water marks on the lens, which may prevent the camera from capturing clear images and negatively impact its functionality. This can also harm the user's perception of the product. Moreover, the water droplets or water marks generated in this case cannot be solved by cleaning the lens externally because it occurs inside the lens. Therefore, how to address water droplets or water marks inside the camera module is a significant issue in the industry. SUMMARY The disclosure provides a camera module including a frame, a camera body, an appearance component, and a transparent cover. The frame includes a first opening. The camera body is disposed in the frame and includes a lens. The first opening corresponds to and exposes the lens. The appearance component is disposed on the frame and includes a second opening corresponding to and exposing the lens and a framing portion protruding from a top surface of the appearance component and framing the second opening. The transparent cover is engaged with the framing portion and covers the lens. The disclosure further provides a method for assembling a camera module, which is described below. A camera body is disposed in a frame. The frame includes a first opening corresponding to and exposing a lens of the camera module. An appearance component is attached to the frame. The appearance component includes a second opening corresponding to and exposing the lens and a framing portion protruding from a top surface of the appearance component and framing the second opening to form an initial camera module. The initial camera module is placed in a non-aqueous airtight cavity. A transparent cover is attached to the appearance component in the non-aqueous airtight cavity to engage the transparent cover with in the framing portion and cover the lens. Based on the above, the camera module and the assembly method thereof of the disclosure use elements such as a frame, an appearance component, and a waterproof adhesive layer to encapsulate the camera body in the frame and the appearance component. Under this configuration, external water and/or moisture may only enter the frame through the opening of the frame configured to expose the lens, as well as through the opening of the appearance component. Subsequently, the transparent cover is attached to the appearance component to seal the opening that exposing the lens. Moreover, the process of attaching the transparent cover is performed in the non-aqueous airtight cavity to prevent external water and/or moisture from entering the frame during assembly, thus effectively avoiding the problem of water droplets or water marks inside the camera module. Therefore, the camera module and the assembly method thereof of the disclosure may effectively improve the yield and the performance of the camera module.
